Sync Voltage PC-Socket vs Hotshoe?

There is some confusion about the max safe sync voltage. The cameras owners manuals is not clear on this matter leaving some to believe that the 250v (on newer DLSRs) is only safe for the PC socket with the hotshoe still at 6v like the older cameras. I would think that they share the same circuit and 250v is safe for the hotshoe also. Can someone give me a definite answer?

The maximum voltages that the hotshoe and the PC terminal can handle are not the same.  The maximum voltage the hotshoe can handle is 6 Volts, while the PC terminal can handle 250 Volts.
